COOLING DEVICE FOR THE MOTORS OF MOTOR-CARS.

Specification of Letters Patent.

Patented March '9, 1909.

Application filed July 28, 1908. Serial No. 445,834.

T all whom it may concern:

Be it known that we, MAURICE GOUDARD and MARoEL MENNEsson, both of 16 Avenue Jules J anin, in the city France, mechanical a Cooling. Device for the Motors of Motor- Cars, of which the following is a full, clear, and exact description. 7

This invention has for its object a cooling device with force air circulation for themotors of motor cars. This cooling device comprising a radiator with an internal centrifugal fan is essentially characterized by the fact of Paris, Republic of that the radiator placed at the rear of this motor is separated from the latter by a wall and the casing of the radiator is provided with air inlets arranged either at the front or at the rear .of the radiator thereby allowing radiator a, Figs. 1 and 2, at the center of which is mounted a centrifugal 'fan b and an.

air supply chamber 0 communicating at its periphery with the outer air and arranged at the front of this radiator; the free internal space of the fan a freely communicates with this chamber through a central orifice d Evhich constitutes the aspirating mouth of the The air supply chamber 0 is constituted by a' wall e arranged in front of the radiator and connected to the front face of the latter by apertured surfaces f, wire trellis or gauze.

The radiator is composed of several parts of any kind, leaving between them'empty spaces so as to enable the air forced back b the ventilator to escape through the periphery of the apparatus; this radiator can be provided on its peri hery with a perforated iron sheet or wire trel is g.

In. the shaft of the fan I) is fastened a pulley it around which passes a transmitting builders, have inventedbelt i carried along by a pulley fast on the drivingshaft of the motor car; the fan can be operated by any other suitable transmission system according to the applications.

This cooling device can be secured to any part of the car, for example in front of the dash board, as shown inFlg. 1.

The circulation of air is as follows: The ex ternal air aspirated by the fan or ventilator enters through the apertured surfaces f into the chamber 0, passes through the aspirating mouth (1 into the radiator; this air is thrown by means of the fan over the radiating bundle, then passes out from the apparatus and then through the }periphery of the radiator,

by passing throug the openings of the cas- 111 g.

lhis device has the advantage of removing from the air circulation the several mechanical parts which can be either at the front of the radiator (for instance the motor) or at the rear (for instance the clutches and the variable speed gear) and consequently protect all these parts against the dust de osits. It is to be observed that in virtue of t 's air circulation process, the radiator can be entirely concealed behind the head and can have the same outline as the latter.

Figs. 5 and 6 show a modified form in which the air supply chamber 0 is beneath the dash board it; the radiator is separated from the motor by a Wall e, as in the previous arrangement. v

In the arran ement shown in Fig. 7, the air enters direct y intothe ventilator throu h the opening (1 which is above the das board it; in this arrangement, the air does not undergo any "heating whatsoever before entering the radiating bundle and it reaches the ventilator without any loss of charge.

The present cooling device can be made of any shape and sizes and its details of con-' struction may vary according to the several apglications.
